# Stratus JavaScript SDK

# Overview

Stratus is the comprehensive object storage solution offered in the Catalyst Cloud Scale service. You can store data of any format in the form of [Objects](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/objects/introduction/) in containers called [Buckets](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/buckets/name-bucket/). Each Bucket and every individual object in the bucket has a secure [Object URL](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/objects/introduction/#object-url) and [Bucket URL](https://docs.catalyst.zoho.com/en/cloud-scale/help/stratus/buckets/create-bucket/#bucket-url). You can perform CRUD, upload, and download operations on objects stored in the bucket.

### Prerequisites

You need to install the following packages to be able to use the Stratus SDK methods.

```sh
npm install @zcatalyst/stratus
```

> **Info:** Ensure that you have applied the [required authentication configuration](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/auth-config/node-consideration/) to use the SDK methods of this component.

### Import Requirement

You need to import the following module to use the Stratus SDK methods.

```javascript
const { Stratus } = require('@zcatalyst/stratus');//Stratus module
```

### List of SDK Methods

The following table contains the list of SDK methods that can be used to perform Stratus operations through code.
